tion of a disinfecting device. It has for an object to provide sucha device whichcan be easily erected in :any convenient situation.

It is .a particular object to provide a device of this character which .is :adaptable to use with either liqnidpor powder disinfectant.

A further important object is to give ;a device of this character which will not tend to waste the disinfectant, and will tend to cause .a fowl .to leave the device as soon .as it has been subjected to one treatment. 7 7

An important .aim of the invention is to give an improved mounting and construe tion for such .a device, and it is an especial advantage thereof that it is adjustable to accommodate 'fowls of different \weight, the

weight :of the fowls 'being .used to operate the device.

My appliance has also the advantage that it induces a considerable amount of exercise in fowls, and may be used for that purpose alone, when not employed as disinfectant device.

It is a particular object to give a desirable construction .a device for automatically spraying a fowl with powder or liquid disinfectant. It is .also an aim to give .a desirable, specific construction in a fowl operated blowing device. Another object is to give an improvement in nozzle devices for such purposes.

Additional ob ects, advantages and fea- .tures of invention will appear in the construction, arrangement, and combination of parts hereinafter set forth, shown in the drawings, where Figure lis .an elevational view of a device constructed in accordance with my invention, 4

In order that the device may be conveniently used either out of doors or in a poultry house or -other place, it is :mounted upon a board 10, with a cross piece 11, forming a base somewhat in the form of the letter T. The appliance in this embodi- Jnent includes a resiliently supported lever '12,. normally extending diagonally upward toward its forward end, where -a short transverse perch 13 is provided. WVhat 1 term a ,putf ball 18 is associated with the base of the lever in such manner that oscillation of the lever in one direction will compress the ball, blowing air through the lever itself,v

fowl being headed toward the base of the lever. A V V The mounting of the lever in the present case comprises a heavy strip of sheet metal having its central portion bent so as to form a a partly cylindrical portion 16, the end portions being abruptly turned outwardly in a common plane to :set snugly upon the upper surface of the board 10, and at a distance from the first point of outward bending the end portions are bent upwardly and inwarclly and attached to the adjacent circular portion forming braces 17. The circular part has snugly fitted therein a rubber ball 14, which is preferably supported on the interior a suitable spring 19 to hold it distended, and the ball is provided with a suitable connection at one side, as at 20, from which a hose 21 is led. The metal 16 is resilient, and at the forward side is slitted as at 22, forming a spring tongue 23, which may be pressed inwardly to bear against the ball for expulsion of its contents. The tongue 23 has secured thereon a suitable heavy plate 24, provided with a centrally recessed boss 25, interiorly threaded, in which is screwed a section of pipe 26, forming the inner or lower end of the lever 12. The boss 25 is provided with a lateral extension or nipple 27, having an opening therethrough communicating with the bottom of the recess in the boss 25, so that communication with the interior of the pipe 25 may be formed through this nipple. The

hose 21 is fitted over the nipple, so that when or collar 28, screwed thereinto, in order to tighten the pipe 27 upon the one 26 and hold it in adjusted position. Suitable packing means may be provided as at'29, or elsewhere in the telescopic joint, as found desirable. Engaged upon the pipe 26 inwardly of the collar 28 there is a slidable collar 30, having an eye 31 at its upper side for engagement of a cord'or cable 32, which is extended therefrom upwardly over a pulley 33 and downwardly a distance immediately inward of the outer end of the pipe section 27, to support a cabbage head 34 or other suitable food, for a purpose to be explained. The collar 30 is also provided cured in adjusted positions.

Slidable upon the outer part of the pipe section 27 there is a collar 36 secured by means of a binding screw 37 and having trunnions 38 extending horizontally at each side, on which there are pivoted arms 39 carrying a short perch 13, before mentie 4O spaced intermediately thereof, a lug 41 being provided on the collar 36 to engage this cross tie to limit pivotal movement of the perch toward the outer end of the pipe 27. The perch is kept yieldably in this position by means of a small spring 42' connected to the arm 39 at one side and having an arm 43 bearing slidably upon the collar 36 at its inner part. The outer end of the pipe 27 is threaded and has engaged thereon the nozzle before mentioned, the base of which is suitably enlarged and interiorly threaded for engagement on the outer end of the pipe 27. The construction of the nozzle may be of any suitable and well known kind used for the purposes in view, there being well known devices for spraying powder and also others for spraying liquids which may be adapted, as required. It is to be noted that in the ini tial position of the perch 13, its forward edge is very close to the tip of the nozzle, this edge of the perch being recessed to prevent the tip of the nozzle from being closed. The tip of the nozzle is located indefinitely upon the perch.

approximately 011 a level with the upper side of the perch, although this exact rela tion 1s not essentlal.

In Fig. 7 there is shown a modification of this device with respect to the mounting of the lever, in which the inner section 26 of the pipe is carried upon a hinged tongue '23, movable in the circular part 16' of a rigid base element similar to that first described. I11 this case, the pipe 26 is 'inounted as before described, but the puff fball 14 is provided with a neck portion 50, extended through a suitable opening in the hinge plate. The neck portion 50 is extended through a suitable opening in the hinged plate, and into the boss 25 upon which the pipe 26 is screwed. The

'neck of the ball is secured tightly in any suitable manner-to prevent escape of air "the'rearound; 1n the present case, a metal collar 51 being inserted in the neck, so

as to pack it tightly against the inner sides "of the boss 25 ball a suitable inlet and check valve 14 is provided, of any suitable kind. A similar check valve may be utilized with the vari In the side of the puff ous other forms of the device, if desired,

although it is thought that it may be omitted in some instances and replenishment of air in the ball effected through the V nozzle, without detriment. with a set screw 35 by which 1t maybe se- In use, the device is installed substanand to the rear of the perch 13. The pulley 33 may be suspended from any I I other suitable support. 1 tioned. The arms are connected by a cross In practice, the perch is held yieldably Eat an elevation of eighteen inches or more above the floor, according to the size and character of the fowl by action of the spring tongue 23, or the spring 55, shown 34 is adjusted at a distance above the perch when in 1n1t1al posltion, such that when a ffowl when standing upon the perch in this 13081131011 may reach the food and partake thereof.

The strength of the resilient means supporting the lever 12, however, is such that as soon as a fowl jumps upon "the perch, the lever will be borne downwardly and this drawing, upon the cabbage 34 will lift the food out of reach of the fowl, so that the fowl will not remain Opportunity is thus given a large number of fowls to gam access to the perch in succession and be treated with disinfectant desired and the fowls are also induced to take exercise at frequent intervals in theiraendeavors to reach the food 34.

It is apparent from the toregoing ,that an extremely simple and inexpensiye rfowl disinfectant and exercising device provided of a durable character and lildihpted to be produced at a low cost- It sh d be noted that when th ow leaps upon the perch 13, the perch swings forwardly with the momentum of the fowl, so that the fowl becomes so positioned that the disinfecting action of the deyice is made highly etlicient upon those areas of the :hody

of the fowl most desired. In Fig. 8 there is show particular {form of nozzle dapted to operate efficiently with my appliance, and to insure eflicient discharge of disinfectant. The-nozzleinthisinstance comprises a bod casting 45 adapted to be screwed on the end of .a pipe as desired, and having a .-suitable duct therethrough. The outer end of the nozzle body is tapered .and pointed upwardly so as to direct .material passing :therethrough, .properly, and at its base is provided with a spring pressed valve 46, by which ingress of air from the pipe 27 through the nozzle tate thepowder if such he used under movement of the pipe 27 downwardly when a fowl gains the perch 13. When powder is used, the ball 49 does not require to :be of a height to engage over the inner end .of the nipple 48 within the reservoir 47.

In :Fig. 9 there is shown a modification of the mounting of the device with respect to the puff ball, which consists in providing a suitable supporting frame 50 in which the puff ball 51 may be set, including standards 52, upon which there is pivoted diametrically over the ball a swinging bracket arm having movement to engage the ball and being nearly or quite concentric with the ball at one position. The ball is formed with a small neck 54 inserted through an opening in a partly spherical plate 55', mounted on the end of a pipe 27 corresponding to the pipe 27 before described.

In Fig. 10 there is shown a further modification of the device in which a pipe 27 is utilized for the function of the pipe 27, the lower end of the pipe only being shown, this being extended in form of a loop 57, engaged around a suitable sleeve 58 engaged revolubly upon a shaft 59 carried in standards .60 upon the baseboard 6.1. The elOWQI end of the pipe 27 is extended inwardly --bey-ond this 210013 .a distance, .a d the down- .wardly as at 62, where it is provided with a centrally apertured normally horizontal disk 63, through which the outlet 1601! .of .aibatlil 64: is engaged, thehall inthis instance simply resting upon 7,116 board :61.

In Fig. 1 there is shown a :form of nozzl suitable tor ,use with the device in such constructions as illustrated in Figs. 8 and ,9, this nozzle comp ising .a base .portion 65 having an outer end interiorly threaded for engagement on the end .of the pipe, the inner part being suitably shaped to provide a seat for a spring .66 disposed therein and bearing toward the open .end of the base upon a ball s67 iooselysdisposed therein. An annular nut 68 is screwed into the threaded part of the base into engagement with .the ball to form .a seat therefor, by which means passage of air through the nozzle is resisted until itreaohes beyond the desired pressure. The -.nut168 is small enough to leave room for the engagement of a pipe in the end .of the nozzle outwardly of the nut. The nozzle is extended vertically downward norreally, from adjacent the spring 66, where it is then .curved ,upwardly and tapered as at :69, as may he found desirable. In the V-bight 70 formed at the lower part, a suitable internally threaded extension 71 is formed, extending horizontally, into which the pipe .or nipple .48 before described may be screwed.

In Fig. 12 there is shown .a form of container for disinfectant suitable for use with the nozzle previously described, consisting of a simple rectangular box 72, having on one end an outlet nipple 73 adapted to screw into the extension 71 of the nozzle, and provided with a valve seat 74 therearound at the inner side through which there is inserted a needle 7 5, having a valve portion 7 6 at its base, the stem 77 of which extends longitudinally through the box and is threaded in a suitable fitting 78 at the end ofthe box opposite the nipple 7 3. The stem projects from the box adjacent the fitting 78, and has a lock nut 79 engaged thereon by which it may be secured in adjusted po sition. A cross pin 80 is engaged through the outer end of the stem 77, by which it maybe turned for adjustment. A plurality of balls 81 are disposed loosely in the box 72, so that in operation. of the device by a fowl, the balls will roll about, and the contents of the box will be agitated.
